The safest way to completely remove the cortex from under the iris superiorly is with the angulated aspiration-irrigation handpiece. It is recommended that a .3 or .5 handle be utilized in low aspiration. As the instrument is rotated around its axis the opening of the aspiration handpiece is up, the cortex is grasped, and the surgeon is able to stay away from the posterior capsule. The incidence of vitreous loss is markedly reduced.
从虹膜上方完全移除皮质最安全的方法是使用有角度的抽吸冲洗机头。建议在低吸力时使用0.3或0.5的手柄。当器械绕其轴旋转时，抽吸机头的开口向上，皮质被抓住，并且外科医生能够远离后囊。玻璃体丢失的发生率显著降低。
